being that i've been tinting windows for 18 years now i think i should reply to this. you didn't say what kind of car you have but most CARS don't have privacy glass from the manufacturer. suv's and minivans do some crossover vehichles do have it but it depends on the model.
the factory tint is such that the glass is made that color when it is made, no factory tint is on the front windows of any car or suvs period. if you bought a brand new car and it has some tint to the front doors it is because it was done at the dealership, aftermarket. there is however a slight color in tempered glass due to the fact that it is heated very rapidly and cooled then heated again numerous times, it can "burn in a color" due to this process but it is in no way to be considered factory tint.
since you live in mass i believe the laws for front windows is 50% which would not match the back windows. that might be what the shop did because they might not tint "illegal" for your state, or they might have used a 35% or a 30% which would still be lighter than your back ones. the tint will not get darker as it dries and you should wait 2 to 3 days since it is cold up there for it to cure and the water bubbles will clear up as this happens.
